transmission input shaft question

[dennismafo]

1975 bay window
I have pulled the upright engine that the last owner put in
poorly i might add
and i am installing a new 2.0L

i have a question about the input shaft

anyone know what it should measure?
is there anyway he could have put that upright in and not replaced the shaft?
I see you can cut them down 11mm to get it in but this one does not look cut

if i need one any leads on where to find one?
he had it hanging off the transmission with 3 bolts no support bar no tin

thanks

weddle has them

Even if yours is cut I'm not sure it would matter. Maybe someone else knows

If I am reading this right the input shaft you have now is to accommodate the installation of a type 1 engine in your '73 bus. And now you are going get rid of that engine and return to a type 4 engine like it is supposed to have.

If this is the case you need to replace the input shaft back to the longer style input shaft that came on the '73 transaxle originally. If the input shaft you have now was cut down or replaced with the shorter version for the type 1 powered buses (68 to 71) it matters not. It is still too short to be supported correctly if at all by the pilot bearing in the end of the type 4 engines crankshaft, and will have bad effects on the operation of the clutch.

No shortcuts or tricks in this case. Just strait out replace it with the right part.

I have seen pilot bearings pressed directly into the flywheel when a type 4 is used in a Beetle, it's nothing that comes off the shelf though, requires a skilled machinist to fabricate and install.

Easier to measure yours and replace it if it's short.

On a Bus Type 4 engine and tranny the pilot bearing runs out near the end of the pilot shaft. If the shaft is for a Type 1 engine it will be too short to run with with the Bus Type 4 engine. You will either need to get a longer pilot shaft or have the flywheel machined to accept the pilot bearing as per some other uses of these engines. Not sure that that is a good idea if you have a cast flywheel though as you would not be leaving a lot of meat around the bolt holes.

ok i will measure it tomorrow thanks for all the great info

Here is a couple before after shots of my bus

enjoy

[dennismafo]

on a side note any info on installing the new one if we have to replace it?

also any other other seals parts etc for swapping this out?
thanks a lot guys its been years since i sold my last 3 vw bus's
and i am a bit rusty

I am gonna guess i have to open the trans up...

[SGKent]

it is a simple task after you get the correct input shaft. You will also want to look at the bell housing to be sure it is the correct one for the flywheel you are installing with the 2L. You may have the wrong Bell housing for a 2L. Weddle has those too. Photos of the flywheel side of the engine and the transmission would be helpful.

ok great
I will get pictures tomorrow the bus is sitting a hour away from me
I have a diesel tech helping me finish this off
but he is not a VW guy he will get it running if i can figure out the rest

thanks for that hook up on the part i found the shaft i will go find the housing now
i assume i can just swap out the housing as well
the trans runs great don't want to replace it just yet

thanks everyone for the help
and wish me luck lol

This is what i am working with
any thoughts does it look like this will work the shaft is out past the bell housing..

[SGKent]

my instinct is that is an early 002 transmission and if so it won't play well with a 2L.

The flywheel on your 2L needs cleaning or surfacing depending on how deep the rust is.

Below is an 091 transmission which was used on the 2L motors. If you count the ribs there are 6. You will also notice two ears at the top of the bell housing closest to you in the photo. See if how many ribs your transmission has and check to see if it has ears on it.

Here is the transmission
I have no clue if this is right for the 2L i have to go in it

[SGKent]

to me that looks like a 5 rib. Does the bell housing have the two ears on it at the top as mentioned?
